A gene regulatory network may be a collection of molecular regulators that interact with one another and with other substances within the cell to control the organic phenomenon levels of mRNA and proteins. The genomic changes can differ markedly between individual cancers, even within a specific cancer type, individual tumours often display wide variations. Heterogeneity of cancer or cancer cells is that the well observed phenomenon and is taken into account the main hurdle for successful treatment. The assessment of inferred networks is a crucial and sophisticated topic. the rationale for this is often that networks are high-dimensional, structured objects that enable modeling of diverse aspects of biological systems.
